Following the long, controversial, and revealing campaigns, United States citizens will head to the polls today to vote for the next president of the country.

The race is between two main candidates, Democratic Party’s Hillary Clinton and Republican Party’s Donald Trump. An independent contender, Gary Johnson of Libertarian Party is also in the race for the 45th president of the United States.

Both Hillary Clinton and Donald Trump raced through several battleground states on Monday in a last-ditch attempt to encourage their supporters to show up and vote on Tuesday.

Clinton sought to capture more support from Latinos, African-Americans and young people, while Trump looked to win over disaffected Democrats and rev up a middle class that he said has been sidelined by the political establishment.

Clinton held the biggest rally of her campaign in Philadelphia on Monday night, drawing a crowd that the city’s Fire Department put at 33,000 to hear her and President Barack Obama, first lady Michelle Obama and rockers Bruce Springsteen and Jon Bon Jovi.

“Tomorrow we face the test of our time,” Clinton told supporters, saying they could decide what sort of country they wanted to live in. “We choose to believe in a hopeful, inclusive, big-hearted America.”

Obama, who campaigned earlier in the day for Clinton in Ann Arbor, Michigan, reiterated his charge that Trump is “temperamentally unfit to be commander in chief,” and said Clinton offered an experienced and accomplished alternative.

“You don’t just have to vote against someone, you have someone extraordinary to vote for,” Obama said. “She will work and she will deliver, she won’t just tweet.”

Trump told voters at an evening rally in Manchester, New Hampshire, they had one question facing them at the ballot box on Tuesday.

“Do you want America to be ruled by the corrupt political class or do you want America to be ruled again by the people?” he asked. “Tomorrow the American working class will strike back.”

With only hours left before Election Day, the Clinton campaign was boosted by Sunday’s unexpected announcement by FBI Director James Comey that the agency stood by its July decision not to press any criminal charges in an investigation of Clinton’s email practices while she was secretary of state.

The Reuters/Ipsos States of the Nation project gave Clinton a 90 percent chance of defeating Trump, seeing her on track to win 303 Electoral College votes out of the 270 needed, to Trump’s 235.

With surveys indicating a tight race in Michigan, which Democrats have long counted on winning, both candidates made campaign appearances there. Pennsylvania, another vote-rich state, was also seen as fertile ground by both camps in the closing hours of their campaigns.
